Enable the checkbox for "Synchronize with an Internet time server" and select a time server such as time.nist.gov.
Alternatively, you can set the time at a command prompt or in the login script by using the following command:
Note that either of these approaches will run afoul of the Windows User Account Control feature if enabled. Disable User Account Control to set the time without a prompt or error.
Rather than potentially cause a UAC elevation consent or credential prompt during login processing, the Novell Client simply attempts to synchronize time with the current Windows user permissions. If UAC is enabled, this attempt will likely be unsuccessful. See the Novell Login Scripts Guide
